Answer:
9.5
Step-by-step explanation:
Well the constant proportionality is 9.5 because that is what makes p directly proportional to a, because when h increases, a increases, and when h decreases, a decreases.
I don't know what your asking
For this case we have that by definition the time is given by:
![t=\frac{d}{v}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bd%7D%7Bv%7D)
Where the variable "d" represents the distance and "v" represents the speed.
So, first we need to know the total distance:
![d=(v)(t)](https://tex.z-dn.net/?f=d%3D%28v%29%28t%29)
![d=(60)(8)](https://tex.z-dn.net/?f=d%3D%2860%29%288%29)
![d=480 mi](https://tex.z-dn.net/?f=d%3D480%20mi)
Then, the time for 75mph is given by:
![t=\frac{480}{75}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B480%7D%7B75%7D)
![t=6,4](https://tex.z-dn.net/?f=t%3D6%2C4)
Answer:
6,4 hours
2 1/4 = 2.25 to find the value of one person u do the equation 2.25 divided by 5 which is 0.45 to find your answer you multiply the amount of cream for one person 0.45 by 8 which is 3.6 and 3.6 as a fraction is 3 3/5 so your answer I believe is 3 3/5
m∠AOC = 108°
m∠AOC = 3m∠AOB
⇒m∠AOB = (m∠AOC) / 3 = 108 / 3 = 36°
